Over the past week Leeds United owner Andrea Radrizzani has again brought the issue of Wolves' links with Jorge Mendes to the fore.

The Championship leaders' relationship with the super agent has raised a number of questions this season, after the Molineux side recruited a number of his clients this summer, including the £15.8million signing of Ruben Neves and the arrival of Atletico Madrid forward Diogo Jota on loan.

Radrizzani alerted attention to the issue in the closing stages of Leeds' 3-0 defeat to Wolves last Wednesday evening, with a series of tweets hitting out at their methods.

"We have our own problems but we should play in a fair competition," he posted on the social network.

"Not legal and fair let one team owned by a fund whom has shares in the biggest players agency with evident benefits (top European clubs giving players with options to buy ..why the other 23 teams can’t have same treatment ? We should play all 24 with the same rules and opportunities (it s enough to google it) @EFL ."

And it has now emerged that Radrizzaini has written to the EFL, FA and Premier League for clarification on the link between Wolves' links with Mendes and where it falls into the current rules.

While a number of Championship sides are said to have issues with what has been going at Molineux this season, Radrizzani has been the first to break ranks and the most vocal over the issue.

When Chinese firm Fosun International bought Wolves in 2016, the EFL said there was no conflict of interest in the fact that they also owned a stake in Mendes' Gestifute agency.

And that is likely to be one of the reasons why Radrizzani has taken it upon himself to ask the authorities these awkward questions.

When the Italian purchased his initial 50 per cent share of Leeds in December 2016, he abandoned his directorship and shareholding in football agency Football Capital in good spirit, to ensure that he would pass the fit and proper persons test.

And after seeing Fosun's success after maintaining their shares with the Mendes agency, Radrizzani has now been motivated to act, believing he may not have had to have sold the agency which he ran.

In an interview with the BBC on Monday he admitted that he would be willing to copy Wolves' methods, if the authorities deem it legal.

"I want to understand the rules so I can act like them," Radrizzani told BBC Sport.

"If it's possible I would do the same as it's been proven to be successful for the team. If not I will do as I did in the past, which I'm happy with too."

Earlier on Monday, Wolves chairman Jeff Shi revealed Radrizzani had joined him and Mendes for several lunches in the past.
